Popis: INTRODUCTION: Autologous stem cell transplantation (ASCT) is a well-established consolidation treatment for many hematologic cancers which delivers prolonged survival. A subset of patients’ adequate stem cell harvest is not achievable with a solitary use of granulocyte colony-stimulating agents (G-CSF). Generally, chemomobilization is employed for patients failing G-CSF and its most feared complication febrile neutropenia (FN). MATERIALS AND METHODS: Here, we aimed to investigate the impact of the FN in chemomobilization on apheresis outcomes and engraftment. One hundred and eighty-three patients with the diagnosis of lymphoma or myeloma who underwent chemomobilization between 2015 and 2020 were included in the study. RESULTS: Forty-three patients experienced FN. All patients received G-CSF. All myeloma patients were mobilized with 4 g/m2 cyclophosphamide, but it was heterogeneous for lymphoma patients. The precollection blood counts, harvested CD34+ hematopoietic stem cells (HSCs)/kg, apheresis count, and engraftment durations were recorded. Preapheresis leukocyte and platelet were lower in the FN group (P = 0,004 and P = 0,001). Peripheral CD34 HSCs and total harvested CD34 HSCs were similar among groups (P = 0.25 and P = 0.9). More apheresis was needed in the FN group, but it was not significant (P = 0.07). Undergoing ASCT was similar (P = 0.7); however, platelet and neutrophil engraftment durations were slower in the FN group (P = 0.05 and P = 0.001). CONCLUSION: Harvesting sufficient CD34+ HSCs from patients with FN is still feasible; however, FN treatment should begin promptly, and further apheresis sessions may be required.
